EXTENSlONSHADE-ROLLEIF.

srncrrrcarzon forming part of Letters Patent No. 655,678, aata August 14, mod. Application filed May 29, 1900. Serial No. 18,416. (No model.)

To aZZ whom it may concern:

Be it known that I, J OHN ALLARD, a citizen of the United States, residing at Kewanee, in the county of Henry and State of Illinois,have invented a new and useful Extension Curtain- Pole, of which the following is a specification.

This invention relates to shade-rollers, and has for one object to provide improved means for adj ustably securing the shade to the roller, so that the former may be conveniently adj usted to suit the length of the window to which the shade may be applied. It is furthermore designed to provide for securing the shade without damaging the latter by the insertion of tacks or similar fastening devices and to arrange for the convenient removal of the shade from the roller.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a front elevation of a shade-roller having a shade con nected thereto by means of the present invention. Fig. 2 is an enlarged detail longitudinal sectional View taken through one end of the roller. Fig. 3 is a detail perspective View of one of the fastening-caps for securing the shade to the roller.

Corresponding parts in the figures of the drawings are designated by like characters of reference.

Referring to the accompanying drawings, 1 designates the roller, which may be a metallic tube, as shown in the drawings, or an ordinary wooden stick, as may be desired.

Removably fitted to each end of the roller is a fastening-cap 2, which is cylindrical in shape and is provided with a plurality of longitudinal slots or incisions to form the spring tongues or fingers 8, which are designed to embrace the adjacent end of the roller, as shown in Figs. 1 and 2. Extending transversely across the inner end of one of the slots or incisions in the cap is a lateral slot 4110 form a bayonet-slot for the reception of a headed stud or pin 5, projecting out from the roller, whereby the cap may be held against longitudinal displacement from the roller.

To secure the shade 6 to the roller, the for mer is folded or Wrapped upon the roller, after which the caps are applied to the opposite ends of the roller, so that the spring-fingers thereof may embrace the respective longitudinal edges of the shade, which is wrapped upon the roller, whereby the former is held to the roller without being damaged by the insertion of tacks or the like and the roller is also protected against similar damage. It will now be apparent that the shade may be rolled upon the roller as much as may be re quired to adjust the shade to the length of any particular window, and when the shade is partly rolled up it covers and conceals the spring-fingers of the fastening caps.

The outer end of each cap is provided with an enlarged cylindrical head 7, which. is hollow, so as to form a box or casing, and is provided with a fixed outer end or cover 8. Extending loosely from a central opening in the inner end of the head is a pintle or journal 9, which projects outwardly through an opening 10 in the center of the cover, so that the outer end of the pintle may be supported in an ordinary roller-bracket. (Not shown in the drawings.) Housed within the hollow head or casing is a coiled spring 11, which haslits inner end connected to the pintle and its outer opposite end connected to the casing, so as to provide a spring-actuated roller. Pivoted to the inner side of the cover or outer head of the casing is a pair of pawls or dogs 12, which are arranged for engagement with a ratchet-disk 13 upon the pintle,whereby the spring and the ratchet device are all housed and protected within the hollow head of the cap. I

' What is claimed is- 1. The combination with a shade-roller, having studs adjacent to the opposite ends thereof, of a shade having one end rolled upon the roller, and opposite fastening-caps fitted to the respective ends'of the roller and embracing the adjacent edges of the rolled portion of the shade, and also provided with bayonet-slots receiving the respective studs,

whereby the caps are fixedly held upon the roller.

2. The combination with a shade-roller,

- having lateral studs adjacent to the opposite ends thereof, of a shade having one end rolled upon the roller and between the studs, and opposite tubular fastening-caps fitted to the respective ends of the roller, and provided with a plurality of longitudinal incisions or slots, forming spring-fingers to embrace the adjacent edges of the folded portion of the
